Help with my CEL

P0135 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)

I have replaced both o2 sensors, double check numerous of times to make sure the wiring was right, and I have replaced my cat and I'm still pulling this code.

I have NO IDEA what to do or where to go from here. I need to get my car registered but it wont pass until this CEL goes away.

And yes I have tried resetting the ECU

Check page DI-56 in the Volume 1 tech manual. You can find volumes 1 and 2 in the TECH INFO section.

I heard that even if u fix the issue, your CEL won't go off without one of those machines that tells u the problem in the first place.

your cel will go off when the problem is fixed, and you reset your computer. you're talking about a reader which can turn reset your computer without unplugging the battery. but, if it reruns your diagnostics and your problem is still there, the CEL will turn back on.

basically, you can use a reader to reset your ECU or just disconnect the battery. whatever floats your boat. i just disconnect my battery.
